Redirecting issues – site wont load

Hi, I have kindly been given some code to redirect all logged out users to my home/landing page (with a few page exceptions like ToS & PP etc.)

However, when I come to load the site in IE, I get:
•Make sure the web address http://carfreaksunite.com is correct.
•Look for the page with your search engine.
•Refresh the page in a few minutes.

In Chrome:
This web page has a redirect loop

In Firefox:
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

Can someone please explain why this is?
I have been told it is because my site is not on the $world_pages “safe” list (whatever that is..?), I have tried to Google it but can’t find anything of relevance..

P.S.
This is the code I was provided with:

add_action('init','boot_non_users');
function boot_non_users() {
  $world_pages = array(106,101,105,102,70,82,50,67,103,104);

  if (!in_array(get_the_ID(),$world_pages))
     if (!is_user_logged_in())
        wp_redirect('http://www.carfreaksunite.com');
}
